Applieeten ile@ November 2, 1%5.- ,Serial No 66,255-

This invention relates to measuring devices especially adapted tor liquids but capable oi also measuring solid material whenV in Ydivided or fragmentary condition.

rlhelenibodiment ot the invention illusf trated is especially designed for Weighing and recording the Water fed to boilers, but the invention is, ofcourse, capable of Wide general eea-.ete fer meeeures and r'eishes devices of all kinds.

' The main object of this invention is to provide an extremely .simple and inexpensive but highly i eiiicient measuring device provided with positive means operated by eren-ty fer eetereetieelly weighing end registering the number of units of material dis ensed.

llt is a further object to provvide such a ldevice having a movable frame hopper iievielefl with tire .eemreftmente :Sie ,meent ed that said compartments will be successively illed and dumped by the accumulation 'of a certain amount of material therein, thereby discharging predetermined amounts-of' material Iat intervals, the move- Dieet ef seid' herne-r being ereretively connected to mechanism to' register ,the number oi units dispensed.

`yIt is an additional object to provide a measuring devee empleyins e seeker-.ble frame Previded with tive' eempertments te leeeiYe end discharge materiel and Support ing means for said rochable frame capable et holding Seid .ff-eine in tilted position te receive dispensed material With the vertical center line of one o the compartments at the side ot' the point ,of `support of the iframe, whereby, when a certain amount of material has accumulated in ,the GQIllPart- Dient diSPeSed te' .leeeve the frame, will be automatically rocked tothe opposite tilted position, the material discharged in so doing and the opposite compartment brought into receiying position.

These and v,other objects of the invention will be apparent from the following description made in connection Withjthe accompanying drawings, wherein like characters refer to similar parts ,throughout the several views, and in which,

Fig. f5 is vertical section thru a trunnion of 4the rocker bar.

In the embodiment of the invention herein illustrated, a substantially rectangular liquid reservoir or tank 46 iS Provided having its top closed by means of the flanged lid and provided with an outlet passage v6a through the bottom thereof. A delivery conduit S is shown mounted Within the topy portion of reservoir 6 provided ivith the valye 9 at its intermediate portion and communicating at its outer end With a spraying nozzle 10 shown inthe form of a. transversely disposed pipe v having through the bottom side thereof a plurality of out- The ends of nozzle 1() are,

let orifices 10h of course, closed, being supported by the sides of reservoir 6. The outer end of delivery member S extends through one side of reservoir 6 being threaded for connection to a` source of Vliquid''supply suoli as conduit A11.

A receiving and discharging member or scale pan 12, comprising a pair of separate trough-like compartments A and B is rockably mounted belovv the delivery nozzlelO. A rocker bar 13 issecured centrally to the underside of k the frame 12 in alignment With theicentral partition 12 ments A .and B. Rocker bar 13 has a flat bOtQm Surface, shaped at its end to form trunnions 13?' preferablyv having beveled sides.` The trunjnions 13' engage and are supported by vthe',COlVeii or arcuate supporting Csurfaces lei 'of upright 'oppositely aligned supports 14 preterably'secured to the sidesotreservoir 6. It ivill also be noticed that support-s 14 provide the vertical abut` ting shoulders 14? at each side of convex supporting surfaces'14*, adapted to abut against the 4,beveled* edges on "trunnions 13e. Obviously the frame member 12 is mounted to rock on supports 14,' limited in its movement by the engagement of shoulders 14? yWith beveled edgesgof ,trunnions 13a, and it is also limitedy in movement ,by means of transe forming compartl versely and obliquely disposed members 15 carried by the opposite sides of reservoir 6 in position to support the respective ends of frame member 12 when in their respective extreme positions. A vertical transverse partition 16 is disposed intermediate of reservoir 6 and adjacent one end of trame 12. A suitable float 1T is disposed in reservoir G at the side otl partition 1G opposite to said rockable frame, operatively connected to valve 9 through the upstanding member 17a pivoted to valve controlling lever 9a.

A counting device 18 of a standard type actuated by the reciprocation of an arm 18- is carried on one of the outer sides of reservoir 6 substantially aligned with supports 14. A substantially elliptically shaped slot- 19 is formed in the side of reservoir 6 above counting device 18, through which a rela`v tively small pin 2() vvorks, carried at one 'end of rocker bar 13. Pin 2O is slidably connected to the reciprocating arm 18a of said counting device, whereby the reeiprocations or rocking of frame 12 may be registered on the reading 'tace 18b of said counting device.

The operation of the device may be brietiy summarized as follows: Assuming trame 12 disposed in extreme rocked position with compartment B in position to receive from nozzle 10. it Will be noticed that the rocker bar 13 will engage supporting surface 14 only on its left edge, the adjacent beveled side contacting shoulder 14". It Will also be noticed that the center line of compartment B will be disposed at the side of point of support of rocker bar 13. Due to the Weight oi partition 12a and disposition of the same when empty, frame or scale pan 12 Will be held in this receiving position. Vhen compartment B has been filled to a certain height with liquid from delivery member 8, the center of gravity ot frame 12 Will be changed, more Weight being then disposed at the right side of the point of support than at the lett and frame 12 will rock on its support14f,com partment B discharging its load and the momentum and torce of the discharging liquid being suiiicient to rock trame 12 toits opposite extreme position with compartment A in position to receive. Here again the rocker bar rests on its right knife edge against the right shoulder 14" ot support 14, compartment A. having its vertical center line disposed to the lett side ot the line of support of the rocker bar 18.

The above described. operation will be successively and continuously repeated and the reciprocating' or rocking movement o't bar 18 will, of course, be transmitted to counting device 18 thru pin 2O and its slotted engage ment with actuating arm 18a. The number of complete rocks or reciprocations of frame 12 will, therefore, be registered on the standard counting device 18, ascertainable thru the reading glass 18". The flow of liquid thru delivery conduit 8 .is controlled by means of the float operated valve 9, so that the level of the liquid in reservoir G is maintained substantially standard.

Partition 16 prevents the splash of Water .fir/charging from compartment A from displacing float 1'? while transverse bars 15 limit the extreme rocking positions oi irame 13.

The shape of supporting surface liln and e1 trunnions 18l are, of course, of utmost importance in producing the above described results, since the compartment in position to receive must be held in tilted position with its vertical center line disposed at the side ot the point of sup Jort ot frame 12.

Fronrthe above escription it will be seen that the applicant has invented a simple but highly etiici-ent autoniatic measuring device, :ap-able ot wide general usage and relying on gravity for its positive actuating mechanism.

Extensive actual usage has shown the device to be successful ior all the purposes enumerated. y

It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of parts Without departing :trom the scope of the invention.
